Mozilla Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 do not properly change the source URI when processing a canvas element and an HTTP redirect, which allows remote attackers to bypass the same origin policy and access arbitrary images that are not directly accessible to the attacker. NOTE: this issue can be leveraged to enumerate software on the client by performing redirections related to moz-icon.

Mozilla Firefox 2.x before 2.0.0.18 and SeaMonkey 1.x before 1.1.13 do not properly check when the Flash module has been dynamically unloaded properly, which allows remote attackers to execute arbitrary code via a crafted SWF file that "dynamically unloads itself from an outside JavaScript function," which triggers an access of an expired memory address.

Georgi Guninski discovered that resource: URLs could bypass local access restrictions. Billy Hoffman discovered that the XBM decoder could reveal uninitialised memory.

Mozilla Firefox before 2.0.0.17 and 3.x before 3.0.2, and SeaMonkey before 1.1.12, allow user-assisted remote attackers to move a window during a mouse click, and possibly force a file download or unspecified other drag-and-drop action, via a crafted onmousedown action that calls window.moveBy, a variant of CVE-2003-0823.
